As I'd be the person making any changes to the default action lists on simcraft, let me follow this up with a few suggestions when doing this:

1: Please try to keep action lists simple, don't add multiple and/or parts to a single line (if buff A + B are up and you are enraged and you have this ability available and... etc etc.). Even if this leads to a minor dps increase, it'd have to be fairly substantial (50-100 dps) to make it worth adding to the official action list.

2: Don't waste your time optimizing the arms profile, you'll just pull your hair out. The spec itself is so error tolerant that it almost doesn't matter how you play, it'll be 95-99% optimal.

3: I doubt it's possible to squeeze much more out of the single target fury action list, the aoe action lists are a better place to start.

Also, use for the action lists. Spoiler will add a bunch of random spaces and fuck it up. Dont' forget to list the cooldown section.
